Why anyone would want to copy that awful inner mouth I have no idea. I agree with PJF and just want to say that stealing is wrong, please don't steal. About Layers: We can make and distribute a difference layer as a photoshop file, but not everyone has photoshop. therefore, would it be hard/impossible to write a program like Mover so that people could encode and decode difference files between any two bitmaps or jpgs? (being of the same size)? Difference layers are not about tracing, they are about adding or detracting features such as detail. -WTB
